@icedquinn @Untersuchende To my knowledge, mutt has no native proxy. I'm also using this decades old thing now:
[14:00 se7en@lappy ~] > which FetchMailAlive 
FetchMailAlive is a function
FetchMailAlive () 
{ 
    if test -f $CONF_FILE && test -f $FETCHMAIL; then
        if test -f $PID_FILE; then
            if ! kill -0 `cut -d \  -f1 $PID_FILE` 2> /dev/null; then
                eval $($TSOCKS $FETCHMAIL);
                echo New FetchMail started. 1>&2;
            fi;
        else
            eval $($TSOCKS $FETCHMAIL);
            echo New FetchMail started. 1>&2;
        fi;
    else
        echo Fetchmail not installed or configured properly. 1>&2;
    fi
}
 
Now my only problem appears to be that mutt has lost the ability to modify flags, and opens in Read-Only Mode (regardless of torify)
